This inventionrelates to certain'new and useful'improvements inaccumulator bins for a grain cleaning machines and the'like; p

a The primary object of the invention is to I? provide an accumulatorbin for grain cleaningmachines wherein the grain dropped into aihopperandconveyed to a pointfor discharge into a machine is controlled in itsflow v to the machine-with an accumulator bin to 1 receive excessgraindelivered to the machine for returnto the hopper," permitting theregulation of feed at themachine rather than at the elevator bootand-permitting an operator to'perform other duties while the grain col-,lected in the accumulator bin is returned to V I the hopper forre-delivery to the machine' by graincleaning machine, it is of courseadapt- 'ed to' 'iis'e with other typesjof machines handling granularmateriahi "clippers, separators, etc.
